摘　　要：本文以柯柯牙绿化工程区为研究对象,耦合MCCA-InVEST模型对多土地利用情景下碳储量特征状况进行分析。研究结果表明:①MCCA模型模拟精度较好,适宜未来土地模拟;②除2050年现状发展情景外,未来不同年度3种发展情景碳储量均表现为增加趋势,且生态优先情景增长幅度最大。本文对区域生态安全及“双碳”目标下土地利用效率的提升具有重要意义。Taking the Kekeya greening project area as the research object,the MCCA-InVEST model is coupled to analyze and study the characteristics of carbon storage under multiple land use scenarios in this paper.The results show that:①The MCCA model has good simulation accuracy and is suitable for future land use simulation.②In the three development scenarios in the future,except for the current development scenario in 2050,the carbon storage shows an increasing trend,and the ecological priority scenario has the largest increase.This paper is of great significance for regional ecological security and the improvement of land use efficiency under the“carbon peaking and carbon neutrality goals”.
